WFOE Environmental Economic & Research Development

Sustainable Engineering Group conducted applied energy efficiency research for the Wisconsin Focus on Energy EERD Program. The purpose of this field study was to evaluate the energy performance of three modern building technologies (displacement ventilation, radiant systems, and variable refrigerant flow) and compare their measured performance to anticipated energy savings.

Our methodology consisted of reaching out to over 100 industry contacts to identify 123 potential candidate buildings containing one of the three technologies. Building owners were contacted to request their participation. A pointed survey was developed to obtain information on design expectations, system performance, occupant comfort, and building energy consumption. Completed surveys were collected from over 30 participants.

Energy Star Target Finder (i.e., the CBECS database) was utilized to benchmark building performance and compare to design expectations for 19 buildings. Data analysis, statistical testing, and data visualization were completed using the python programming language. ASHRAE Phase 1 Energy Audits were conducted on nine of the participating buildings (three from each target technology) to evaluate building systems and operation. A final report was produced and reviewed by project stakeholders.
